Ablation and Viscous Effects on the Force and Moment Characteristics of Slender Cone Models at Mach 10 under Laminar Flow Conditions

Abstract

A comprehensive wind tunnel investigation was conducted at Mach number 10 on 4- and 5-deg half-angle cones in order to study ablation and viscous effects under laminar flow conditions. Attention was focused on (1) the mode of ablation simulation, (2) obtaining consistent pitch plane force measurements in the angle-of-attack range from 0 to 4 deg, (3) the effect of bluntness, and (4) viscous effects over as large a Reynolds number range as possible. The subliming ablator used was camphor, which is compared to blowing through a porous surface using (1) nitrogen, (2) argon, and (3) sulphur hexafluoride (SF6) gases.
